I'm also taking a look in this one, I couldn't reproduce it (tried 11 times, with the same az-cli command-line provided by gjolly. Found 2 interesting things after Gauthier provide me access to one of his failing instances:
(a) Regarding cloud-init, I see the following in the logs (comparing a GOOD and BAD instance): GOOD: 2021-04-13 19:19:09,341 - DataSourceAzure.py[DEBUG]: Retrieving public SSH keys 2021-04-13 19:19:09,341 - azure.py[DEBUG]: Unable to get keys from IMDS, falling back to OVF 2021-04-13 19:19:09,341 - DataSourceAzure.py[DEBUG]: Retrieved keys from OVF 2021-04-13 19:19:09,342 - handlers.py[DEBUG]: finish: azure-ds/get_public_ssh_keys: SUCCESS: get_public_ssh_keys 2021-04-13 19:19:09,342 - util.py[DEBUG]: Changing the ownership of /home/ubuntu/.ssh to 1000:1000 2021-04-13 19:19:09,343 - util.py[DEBUG]: Reading from /etc/ssh/sshd_config (quiet=False) 2021-04-13 19:19:09,343 - util.py[DEBUG]: Read 3287 bytes from /etc/ssh/sshd_config 2021-04-13 19:19:09,343 - util.py[DEBUG]: Writing to /home/ubuntu/.ssh/authorized_keys - wb: [600] 381 bytes 2021-04-13 19:19:09,343 - util.py[DEBUG]: Changing the ownership of /home/ubuntu/.ssh/authorized_keys to 1000:1000 2021-04-13 19:19:09,344 - util.py[DEBUG]: Changing the ownership of /root/.ssh to 0:0 2021-04-13 19:19:09,344 - util.py[DEBUG]: Reading from /etc/ssh/sshd_config (quiet=False) 2021-04-13 19:19:09,344 - util.py[DEBUG]: Read 3287 bytes from /etc/ssh/sshd_config 2021-04-13 19:19:09,344 - util.py[DEBUG]: Writing to /root/.ssh/authorized_keys - wb: [600] 545 bytes BAD: 2021-04-12 08:25:07,412 - DataSourceAzure.py[DEBUG]: Retrieving public SSH keys 2021-04-12 08:25:07,412 - azure.py[DEBUG]: Unable to get keys from IMDS, falling back to OVF 2021-04-12 08:25:07,412 - azure.py[DEBUG]: No keys available from OVF 2021-04-12 08:25:07,412 - handlers.py[DEBUG]: finish: azure-ds/get_public_ssh_keys: SUCCESS: get_public_ssh_keys 2021-04-12 08:25:07,413 - util.py[DEBUG]: Changing the ownership of /home/ubuntu/.ssh to 1000:1000 2021-04-12 08:25:07,413 - util.py[DEBUG]: Reading from /etc/ssh/sshd_config (quiet=False) 2021-04-12 08:25:07,413 - util.py[DEBUG]: Read 3287 bytes from /etc/ssh/sshd_config 2021-04-12 08:25:07,414 - util.py[DEBUG]: Writing to /home/ubuntu/.ssh/authorized_keys - wb: [600] 0 bytes 2021-04-12 08:25:07,414 - util.py[DEBUG]: Changing the ownership of /home/ubuntu/.ssh/authorized_keys to 1000:1000 2021-04-12 08:25:07,414 - util.py[DEBUG]: Changing the ownership of /root/.ssh to 0:0 2021-04-12 08:25:07,414 - util.py[DEBUG]: Reading from /etc/ssh/sshd_config (quiet=False) 2021-04-12 08:25:07,415 - util.py[DEBUG]: Read 3287 bytes from /etc/ssh/sshd_config 2021-04-12 08:25:07,415 - util.py[DEBUG]: Writing to /root/.ssh/authorized_keys - wb: [600] 0 bytes So, the main difference here is: 2021-04-13 19:19:09,341 - DataSourceAzure.py[DEBUG]: Retrieved keys from OVF vs 2021-04-12 08:25:07,412 - azure.py[DEBUG]: No keys available from OVF Why one method executes from DataSourceAzure.py whereas the other from azure.py? I'm far from expert in cloud-init, so I'll defer that questions to cloud-init folks.
